. CANOE-FORM.

Patented sense-1919.

'Application led January 12, 1918.- Serial No. 211,596.

lfb all whom t may concern:

Be it known that I, PETER THOMPSON, a citizen of the United States, 'residing at Peshtigo, in the county of Marinette and State of lVisconsin, have invented new and useful improvements in Canoe-Forms, of which the following is a specification.

This invention relates to a form which may be employed inthe construction of canoes to insure the canoe having the required shape when completed.

The primary obj ect of the invention is to provide alform for this purpose which'will extend the entire lei'lgth of the frame of the canoe to be assembled thereonand is so yconstructed that when the frame of the canoe is completed the frame may be removed 'from the form without splitting or straining the frame' which commonly occurs vvwith forms for this purpose now in use.

Another object of the invention is to provide a canoe form having stem members upon which the short rib sections of the canoe and V'stem pieces may be assembled and when connected the stem members may be detached from the body of the form and removed with the frame of the canoe thereby enabling the entire frame of the canoe to be completed before removing the same from the form which can not be done with forms now in use.

A further obj ect of theV invention is to provide the Vform with a body having side members which are hinged together in such a manner that when the Stem members `are detached therefrom the side members swing Ato a position which will allow the body of the form to be easily removed from the frame of the canoe.

A still further object( of the invention is to provide the form with a body having detachably connected therewith va midship section whichmay be removed from the body to enable the form to be used inthe construction of canoes which vary in length.

With these and other objects in view, the invention resides in the novel combination and arrangement of parts, which will be hereinafter described ,and particularly pointed out in the claims. i

' The preferred embodiment of the invention has been illustrated in the accompanying drawing, although no restriction is necessarily made to the precise details of. construction therein shown, as changes, alterations, and modifications, within the scope of the claims may be resorted to when def Y form constructed in accordance with the inv vention. Y

Fig. 3 is a view similar to Fig. 2 showing the sections of the form disconnected.

Fig. l is a detail perspective view of one of the stem members. i.

' Fig. 5 isa perspective view of one of the body sections.

Fig. 6 isa perspective view of one of the mid-ship sections. r v Fig. 7 is a transverse sectional view onfthe line 7-7 of Fig. l.

Fig. 8 is a view similar to Fig. 7 showving the side mem'bers of the bodyV swung to a position to enable thev form to be removed from the frame of a canoe.v f

Referring now to the' drawingsin detail, the numeral l designates the improved ca-V noe form which is in the shape of a'canoe and comprises a body 2, thesections 3 and 4e of which have connected therewith stem members 5, said sections Iand l receiving plan view of the canoe therebetween andV having detachably `cong-V Y nected therewith a midship section 6.

prises side members 7 vand Seach having'av straight side arrangedV in opposed relation,

said members being connected by hinges 9 to enable theside members 7 and 8 to have swinging movement.

rlhe side member 7 has formed on its straight Side a longitudinally extending rib f l0 which limits the swingingmovement of the side member 8 in one directionand also coacts with the side member 8 informing channels Yl1 and 12 extending the "entire length of the body section,gthe channel 11 being adapted to receive therein,`the keelson of a canoe which is being constructed upon,

the canoe form, while the channel 12 may have inserted therein wedges,V or theA like,-y

for spreading they side members 7 and 8,

said wedges being removably held in the channel 12 by buttons 13 pivot-ally connected with the side member 3.

The bottom face oi' each side member 7 and S has extending longitudinally thereof a. strip 13 held in spaced relation with the side member by means of cleats 14, said strips 13 enabling a clamp not shown in the drawings to be connected with the form for holding the free ends of the rib sections in place upon the body sections.

Arranged .between the strip 13 and bottom face oi' each side member 7 and 8 at the smaller end thereof is a keeper 15 secured to the side member in any suitable manner and having one end thereof extending beyond the end of the side member adapted for contact With an end on a stem member and provided with an eye 16.

The ends or the side members 7 and 3 of the body section 3 which are adapted Jfor contact With an end on the body section 4 or withl an end on the midship section 6 are provided with socket members 17 adapted to receive locking studs 18 projecting from the end of the side members 7 and 3 orp the body section 4 when the ends of the sections 3 and 4 are brought into cont-acting relation.

The rib 10 on each body section 3 and 4 has connected therewith at the smaller end oi' said section 'a keeper 20 similar to the keeper 15.

A midship section 6 like the body sections 3 and 4 comprises side members 21 and each having a straight side edge arranged in opposed relation, said members being connected for swinging movement by hinges 23 with the side member 22 having a rib 24 similar to the rib 10 and providing the midship section With channels 25 and 26 adapted to aline with the channels 11 and 12 in the body sections when the midship section is connected therewith to enable the l'orm to be used with canoes the length of which is above the average. t K One end of each side member 9721 and 22 has connected therewith a socket member Q7 similar to the socket members 17 and adapted to receive the locking studs Q8 on the plates 19 on the body section 4 when the midship section is arranged between the body sections at which time looking studs 28 on plates 29 on the other ends of the side members 21 and 22 Willbe received in the socket members 17 on the body section 3, thus detachably connecting the midship section with the body sections and in such a manner that the side members of the midship section will swing With the side members of the body sections with which they are'connected when the stem members are disconnected from the body sections.

Each stem member 5 corresponds in shape to the stem of the canoe and has extending longitudinally thereof in its top face from the end oF the member adapted for conne-ction with an end on the body section, a groove 30 which when the member is connected With a body section registers with the groove 11 therein to receive the portion of the keelson with which the stem strip on the canoe is connected.

A hook 31 is received in the groove 30 on each stem member and has its bill 32 veX- tending beyond the end of the stem member which is adapted to be brought into con-V tact With an end on. the body section. The bottom face of each stem member has se- `cured thereto upon opposite sides 'and adj cent the larger end'o the stem member hooks 33 having bills 34 so that When the larger end of the stem member is brought into Contact with the smaller end otra body section, Vthe bills 34 may be passed through the eyes 16 in the keepers 15 While the bill 32 on the hook 31 will be received in the eye in the keeper 20 thus detachably connecting the stem members With the body sections.

y Each stem member 5 is provided upon its bottom tace with a strip 35 heldin spaced relation With the bottom face by cleats 36, saidstrips 35 providing a continuation of the strips 13 Whenthe stem members are connectedi With the body sections and performing the same function as the strips 13.

All of the sections comprising the canoe 'orm have extending transversely thereof plates 37 which when the planking is being nailed to the ribs of the canoe serve to bend the ends of tbe nails that they provide rivets for holding the planking and ribs connected.

W'hen it is desired to use the canoe form in constructing a canoe and it is not neces sary to use the midship section 6 to enable the form to extend the entire length of the canoe, the body sections 3 and 4 may be connected by inserting the locking` studs 13 on the body section 4 in the socket members 17 on the body section 3. Thestem members may now be connected with the smaller ends the body sections bymeans of the hooks 31 and 33 on the stem members and keepers 15 and 20 on the body sections.

The form may novv be placed upon a suitable support, the channels 11 in the body sections and grooves 30 in the stem members receiving a keelson.

The. longer ribs of the body of the canoe may be assembled on the body sections 3 and 4 and the short rib sections assembled on the stem members 5 and the stein strips bent on the pointed ends of the stem mem bers and connected With the frame of the canoe.

It desired the planking and canvas may novv be applied to the trame of the canoe before Ithe same is Withdrawn from the form.

When it is desired to remove the canoe from the torni7 thestem members are disconnected from the ends of the body sections and the side members swung to a position which will permit the body of the form to be removed from the canoe without straining or bending the frame, it, of course, being understood that the stem members may be retained in the stems or' the canoe as long as desired or may be easily removed therefrom as. soon as the body of the form has been removed :trom the canoe.

When it is desired to increase the length of the form for canoes above the average length, the midship section is arranged between the body sections and connected therewith by inserting the locking studs 28 on the side members or' the midship section in the socket members 17 on the body section 3 and inserting the locking studs 18 on a body section 4 in the socket members on the side members of the midship section so that when it is desired to remove the body of the form from the canoe, the side members or' themidship section will swing with the side members of the body sections.

llt will, or' course, be understood that any number of midship sectionsV G may be iised in connection with the body sections to enable the form to have the required length to allow the complete frameto be assembled thereon ,of a canoe above the average minimum length.

From the foregoing description, ,taken in connection withv the accompanying drawings, it is at once apparent that a canoe 4torm hasbeen provided which comprises few parts which are detachably connected and arranged in such a: manner that a canoe may be assembled thereon in an entirety and the form removed from the canoe ywithout straining or damaging thesame. i

Having thus described the invention, what is claimed as new, is:

l. A canoe form comprising a body, and stem members detachably connectedv with the body.

2. A canoe form comprising body sections detachably connected, and stem members removably connected withthe body sections.
